Answer 1

        List<Ticket> list = new ArrayList<Ticket>();
        list.addAll(ticketRegistry.getTickets());
        for( Ticket x : list )
        {
            TicketGrantingTicketImpl ticket = (TicketGrantingTicketImpl) x;
            String name = ticket.getAuthentication().getPrincipal().getId();
            if(username.equals(name))
            {
                logoutManager.performLogout(ticket);
            }
        }

get the ticketRegistry and logoutManager, find out the name and do performLogout.
